Safety information

ESU10180

When you ride your snowmobile, you must
know and use the following for your safety.
Severe injury or death may result if you ignore
any of the following.

Before operating

1. Read the Owner’s Manual and all labels
before operating this snowmobile. Be­come familiar with all of the operating
controls and their function. Consult a
Yamaha dealer about any control or func­tion you do not understand.

2. This snowmobile was not manufactured
for use on public streets, roads, or high­ways. Such use is prohibited by law, and
you could collide with another vehicle.

3. This snowmobile is designed to carry the
OPERATOR ONLY.
Passengers are prohibited. Carrying a
passenger can cause loss of control.

4. Do not operate the snowmobile after
drinking alcohol or taking drugs. Your
ability to operate the snowmobile is re­duced by the influence of alcohol or
drugs.

5. For safety and proper care of the snow­mobile, always perform the pre-operation
checks on page 29 before starting the en­gine. Check the throttle, brake, and steer­ing for proper operation every time before
starting the engine. Make sure that the
throttle lever moves freely and it returns
to the home position when it is released.

6. Apply the parking brake before starting
the engine. Never drive the snowmobile
with the parking brake applied. This may
overheat the brake disc and reduce brak­ing ability.

7. Do not allow anyone to stand behind the
snowmobile when starting, inspecting, or
adjusting the snowmobile. A broken
track, track fittings, or debris thrown by
the track could be dangerous to the oper­ator or bystanders.

8. Handle fuel with care; it is HIGHLY
FLAMMABLE.

● Never add fuel when the engine is run-

ning or hot. Allow the engine to cool for
several minutes after running.

● Use an approved fuel container.

1

Safety information

● Fill the fuel tank outdoors with extreme

care. Never remove the fuel cap in­doors. Never fill the fuel tank indoors.

● Never refuel while smoking or in the vi-

cinity of an open flame.

● Make sure that the fuel tank cap is

closed securely after refueling. Wipe
up any spilled fuel immediately.

9. If you swallow some gasoline, inhale a lot
of gasoline vapor, or get some gasoline
into your eyes, see your doctor immedi­ately. If any gasoline spills on your skin or
clothing, immediately wash your skin with
soap and water, and change your
clothes.

10. Wear protective clothing. Wear an ap­proved helmet, and a face shield or gog­gles. Also, wear a good quality
snowmobile suit, boots, and a pair of
gloves or mittens that will permit use of
your thumbs and fingers for operation of
the controls.

Operation

1. Do not run the engine indoors, except
when starting the engine to transport the
snowmobile in or out of the building.
Open the outside doors; exhaust fumes
are dangerous.

2. Be careful where you ride. There may be
obstacles hidden beneath the snow. Stay
on established trails to minimize your ex­posure to hazards. Ride slowly and cau­tiously when you ride off of established
trails. Hitting a rock or stump, or running
into wires could cause an accident and
injury.

3. This snowmobile is not designed for use
on surfaces other than snow or ice. Use
on dirt, sand, grass, rocks, or bare pave­ment may cause loss of control and may
damage the snowmobile.

4. Avoid operating on glare ice, or on snow
which has a lot of dirt or sand mixed in.
Operation under such conditions will
damage or result in rapid wear of ski run­ners, drive track, slide runners, and drive
sprockets.

5. Always ride with other snowmobilers
when going on a ride. You may need help
if you run out of fuel, have an accident, or
damage your snowmobile.

6. Many surfaces such as ice and hard­packed snow require much longer stop­ping distances. Be alert, plan ahead and

2

begin decelerating early. The best brak­ing method on most surfaces is to release
the throttle and apply the brake gently—
not suddenly.

Maintenance and storage

1. Do not leave the snowmobile on its left
side for an extended period of time. Fuel
may leak out from the fuel breather hose.

2. Modifications made to the snowmobile
not approved by Yamaha, or the removal
of original equipment may render your
snowmobile unsafe for use that may
cause severe personal injury. Modifica­tions may also make the snowmobile ille­gal to use.

3. Never store the snowmobile with fuel in
the fuel tank inside a building where igni­tion sources are present such as hot wa­ter and space heaters, an open flame,
sparks, clothes dryers, and the like. Allow
the engine to cool off before storing the
snowmobile in an enclosed space.

4. Always refer to the “STORAGE” section
on page 75 if the snowmobile is to be
stored for an extended period.

5. Maintain or replace safety and instruction
labels, as necessary.

Pre-operation checks

ESU11070

The condition of a snowmobile is the owner’s responsibility. Vital components can start to de­teriorate quickly and unexpectedly, even if the snowmobile remains unused (for example, as a
result of exposure to the elements). Any damage or fluid leakage could have serious conse­quences. Therefore, it is very important, in addition to a thorough visual inspection, to check
the following points before each ride.

NOTE:

Pre-operation checks should be made each time the snowmobile is used. Such an inspection
can be accomplished in a very short time; and the added safety it assures is more than worth
the time involved.

Riding your snowmobile

Getting to know your snowmobile

A snowmobile is a rider active vehicle, and
your riding position and your balance are the
two basic factors of maneuvering your snow­mobile.
Riding your snowmobile requires skills ac­quired through practice over a period of time.
Take the time to learn the basic techniques
well before attempting more difficult maneu­vers.
Riding your new snowmobile can be a very
enjoyable activity, providing you with hours of
pleasure. However, it is essential to familiar­ize yourself with the operation of the snowmo­bile to achieve the skill necessary to enjoy
riding safely. Before operating the snowmo­bile, read this Owner’s Manual completely
and understand the operation of the controls.
Pay particular attention to the safety informa­tion on page 1.
Please read all warning and caution labels on
your snowmobile. Also, read the Snowmobil­er’s Safety Handbook that is supplied with
your snowmobile.

Learning to ride your snowmobile

Before you ride, always perform the pre-oper­ation checks listed on page 29. The short time
spent checking the condition of the snowmo-

bile will be rewarded with added safety and a
more reliable snowmobile. Always wear the
proper clothing for both warmth and to help
protect you from injury if an accident occurs.
Become familiar with operating your snowmo­bile at low speeds, even if you are an experi­enced rider. Do not attempt to operate at
maximum performance until you are totally fa­miliar with the snowmobile’s handling and
performance characteristics.
The beginning operator should select a large
flat area to become familiar with the snowmo­bile. Make sure that this area is free of obsta­cles and other traffic. You should practice
control of the throttle and brake, and master
turning techniques in this area before trying
more difficult terrain.
Set the parking brake and follow the instruc­tions on page 31 to start the engine. Once the
engine has warmed up, you are ready to be­gin riding your snowmobile.

To start out and accelerate

1. With the engine idling, release the park­ing brake.

2. Apply the throttle slowly and smoothly.
The V-belt clutch will engage and you will
start to accelerate.

EWS00210

WARNING

The operator should always keep both
hands on the handlebar. Never put your
feet outside the running boards. Avoid
high speeds until you have become thor­oughly familiar with your snowmobile and
all of its controls.

Braking

When slowing down or stopping, release the
throttle and apply the brake gently—not sud­denly.

32

Operation

EWS00220

WARNING

● Many surfaces such as ice and hard-

packed snow require much longer stop­ping distances. Be alert, plan ahead, and
begin decelerating early.

● Improper use of the brake can cause the

drive track to lose traction, reduce con­trol, and increase the possibility of an
accident.

Turning

For most snow surfaces, “body English” is the
key to turning.
As you approach a curve, slow down and be­gin to turn the handlebar in the desired direc­tion. As you do so, put your weight on the
running board to the inside of the turn and
lean your upper body into the turn.

If your snowmobile begins to tip while turning,
lean more into the turn to regain balance. If
necessary, gradually let off on the throttle or
steer to the outside of the turn.

Remember:

Avoid higher speeds until you are thoroughly
familiar with the operation of your snowmo­bile.

Riding uphill

You should practice first on gentle slopes. Try
more difficult climbs only after you have de­veloped your skill. As you approach a hill, ac­celerate before you start the climb, and then
reduce the throttle to prevent track slippage. It
is also important to keep your weight on the
uphill side at all times. On climbs straight up
the hill, this can be accomplished by leaning
forward and, on steeper inclines, standing on
the running boards and leaning forward over
the handlebar. (Also see “Traversing a
slope”.)

This procedure should be practiced at low
speeds many times, in a large flat area with no
obstacles. Once you have learned this tech­nique, you should be able to perform it at high­er speeds or in tighter curves. Lean more as
the turn gets sharper or is made at higher
speeds.
Improper riding techniques such as abrupt
throttle changes, excessive braking, incorrect
body movements, or too much speed for the
sharpness of the turn may cause the snow­mobile to tip.

Slow down as you reach the crest of the hill,
and be prepared to react to obstacles, sharp
drops, or other vehicles or people which may
be on the other side. If you are unable to con­tinue up a hill, do not spin the track. Stop the
engine and set the parking brake. Then pull
the rear of the snowmobile around to point the
snowmobile back down the hill. When the
snowmobile is pointed downhill, mount your

33

Operation

snowmobile from the uphill side. Restart the
engine, release the parking brake, and de­scend the hill.

EWS00230

WARNING

Side hills and steep slopes are not recom­mended for a novice snowmobiler.

Riding downhill

When riding downhill, keep speed to a mini­mum. It is important to apply just enough
throttle to keep the clutch engaged while de­scending the hill. This will allow you to use en­gine compression to help slow the
snowmobile, and to keep the snowmobile
from rolling freely down the hill. Also apply the
brake frequently, with light pressure.

EWS00240

WARNING

Use extra caution when applying the brake
during a descent. Excessive braking will
cause the drive track to lock, causing a
loss of control.

Traversing a slope

EWS00250

WARNING

Traversing slopes is not recommended for
a novice snowmobiler.

Traversing a slope requires you to properly
position your weight to maintain proper bal­ance. As you travel across the slope, lean
your body to position your weight towards the

uphill side. A recommended riding position is
to kneel with the knee of your downhill leg on
the seat and the foot of your uphill leg on the
running board. This position will make it easi­er for you to shift your body weight as needed.

Snow and ice are slippery, so be prepared for
the possibility that your snowmobile could be­gin to slip sideways on the slope. If this hap­pens, steer in the direction of the slide if there
are no obstacles in your path. As you regain
proper balance, gradually steer again in the
direction you wish to travel.
If your snowmobile starts to tip, steer down
the hill to regain balance.

EWS00260

WARNING

If you are unable to maintain correct bal­ance, and your snowmobile is going to tip
over, dismount your snowmobile immedi­ately on the uphill side.

Ice or icy surface

Operating on ice or icy surfaces can be very
dangerous. Traction for turning, stopping, and
starting is much less than that on snow.

EWS00270

WARNING

When you have to operate on ice or icy
surfaces, drive slowly and cautiously.
Avoid accelerating, turning, and braking
rapidly. Steering is minimal and uncon­trolled spins are an ever-present danger.

34

Operation

Hard-packed snow

It can be more difficult to negotiate on hard­packed snow as both the skis and drive track
do not have as much traction as when the
snowmobile is operated on fresh snow. Avoid
rapid acceleration, turning, and braking.

Operation on surfaces other than snow or ice

Operation of your snowmobile on surfaces
other than snow or ice should be avoided. Op­eration under such conditions will damage or
result in rapid wear of the ski runners, drive
track, slide runners, and drive sprockets. Op­eration of the snowmobile on the following
surfaces should be avoided at all times:

● Dirt

● Sand

● Rocks

● Grass

● Bare pavement

Other surfaces that should be avoided for the
sake of drive track and slide runner life are:

● Glare ice surfaces

● Snow mixed with a lot of dirt and sand

All of the above surfaces have one thing in
common in regard to drive track and slide run­ners: little or no lubricating ability. Drive track
and all slide rail systems require lubrication
(snow or water) between the slide runners
and the slide metal. In the absence of lubrica­tion, the slide runners will rapidly wear and in
severe cases, literally melt away, and the
drive track will be subject to damage or failure.
Also traction aids such as studs, cleats, etc.,
may cause further track damage or failure.

EWS00280

WARNING

Drive track damage or failure could result
in loss of braking ability and snowmobile
control, which could cause an accident.

● Always check the drive track for damage

or maladjustment before operating the
snowmobile.

● Do not operate the snowmobile if you

find damage to the drive track.

ECS00350

CAUTION:

Ride on fresh snow frequently. Operating
on ice or hard-packed snow will rapidly
wear the slide runners.

ESU11350

Maximizing drive track life

Recommendations
Track tension

During initial break-in, the new drive track will
tend to stretch quickly as the track settles. Be
sure to correct the track tension and align­ment frequently. (See page 62 for adjustment
procedures.) A loose track can slip (ratchet),
derail or catch on suspension parts causing
severe damage. Do not overtighten the drive
track, otherwise it may increase the friction
between the track and the slide runners, re­sulting in the rapid wear of both components.
Also, this may put an excessive load on the
suspension components, resulting in compo­nent failure.

Marginal snow

The drive track and the slide runners are lubri­cated and cooled by snow and water. To pre­vent the drive track and slide runners from
overheating, avoid sustained high-speed us­age in areas such as icy trails, frozen lakes
and rivers that have minimal snow coverage.
An overheated track will be weakened inter­nally, which may cause failure or damage.

Off-trail riding

Avoid off-trail riding until there is sufficient
snow coverage. It generally takes several feet
of snow to provide a good overall base to
properly cover debris, such as rocks, logs,

35

Operation

etc. If snow coverage is not sufficient, stay on
trails to avoid impact damage to the drive
track.

Studded track

In general, track life will be shortened when
studs are installed. Drilling stud holes into the
drive track will cut the internal fibers, which
weakens the track. Avoid spinning the drive
track. Studs may catch on an object and pull
out of the track, leaving tears and damage
around the already weakened area. To mini­mize possible damage, consult your stud
manufacturer for installation and stud pattern
recommendations.

Yamaha does not recommend track stud­ding.

Transporting

When transporting your snowmobile on a trail­er or in a truck, observe the following recom­mendations to help protect it from damage:

● If transporting the snowmobile in an open

trailer or truck, put a tight fitting cover on the
snowmobile. A cover specifically designed
for your snowmobile is best. This will help
keep foreign objects out of the cooling
vents, and also help protect the snowmo­bile against damage from debris on the
road.

● If transporting the snowmobile in an open

trailer or truck in areas where road salt is
used, coat metal suspension surfaces light­ly with oil or another protectant. This will

ESU11780

Checking the spark plugs

The spark plug is an important engine compo­nent and is easy to inspect. The condition of
the spark plug can indicate the condition of
the engine.
Check the coloration on the white porcelain
insulator around the center electrode. The
ideal coloration at this point is a medium to a
light tan color for a snowmobile that is being
ridden normally. If a spark plug shows a dis­tinctly different color, there could be some­thing wrong with the engine. For example, a
very white center electrode porcelain color
could indicate an intake track air leak or car­buretion problem for that cylinder. Do not at­tempt to diagnose such problems yourself.
Instead, take the snowmobile to a Yamaha
dealer for inspection and possible repairs.
You should periodically remove and inspect
the spark plug because heat and deposits will
cause a spark plug to slowly break down and
erode. Consult a Yamaha dealer before
changing to a different type of spark plug.

Specified spark plug:

Manufacturer:

NGK

Model:

CR9EB

Spark plugs are produced in several different
thread lengths. The thread length or reach is
the distance from the spark plug gasket seat
to the end of the threaded portion. If the reach
is too long, overheating and engine damage
may result. If the reach is too short, spark plug
fouling and poor performance may result. Al­so, if the reach is too short, carbon will form on
the exposed threads resulting in combustion
chamber hot spots and thread damage. Al­ways use a spark plug with the specified
reach.

Spark plug reach:

19.0 mm (0.75 in)

1. Spark plug gap

2. Spark plug reach

Before installing any spark plug, measure the
electrode gap with a wire thickness gauge
and adjust to specification.

Spark plug gap:

0.7–0.8 mm (0.028–0.031 in)

44

When installing the spark plug, always clean
the gasket surface. Wipe off any grime from
the threads and tighten the spark plug to the
specified torque.

Spark plug tightening torque:

12.5 Nm (1.25 m·kgf, 9 ft·lb)

ECS00380

CAUTION:

Make sure that the spark plug caps are se­curely installed. Otherwise the spark plug
caps could be damaged due to engine vi­bration.

ESU11930

High-altitude settings

Operating at high altitude reduces the perfor­mance of a gasoline engine about 3% for ev­ery 305 m (1000 ft) of elevation. This is
because there is less air as altitude increases.
Less air means less oxygen available for
combustion.
Your snowmobile utilizes an electronic fuel in­jection system that delivers the optimal air/fu­el ratio required by the engine. Therefore, the
fuel injection system does not need to be ad­justed, even for operation at high altitude.

Remember:

Less air at higher altitude means there is less
horsepower available, even with the optimal
air/fuel ratio. Expect acceleration and top
speed to be reduced at higher altitudes.
To overcome operating with less power at
high altitudes, your snowmobile may also re­quire different settings for the drive chain
gears and V-belt clutch to avoid poor perfor­mance and rapid wear. If you plan to operate
your snowmobile at an altitude different from
the area where you bought it, be sure to con­sult a Yamaha dealer. The dealer can tell you
if there are any changes necessary for the al­titude where you plan to ride.

ECS00430

CAUTION:

The drive chain gears and V-belt clutch
should be adjusted when operating above
a high altitude of 900 m (3000 ft). Consult a
Yamaha dealer.

ESU11950

Valve clearance

The valve clearance changes with use, result­ing in improper air-fuel mixture and/or engine
noise. To prevent this from occurring, the
valve clearance must be adjusted by a
Yamaha dealer at the intervals specified in
the periodic maintenance chart.

ESU11962

Engine oil and oil filter cartridge

The engine oil level should be checked before
each use. In addition, the oil must be changed
and the oil filter cartridge replaced at the inter­vals specified in the periodic maintenance
and lubrication chart.

EWS00370

WARNING

Engine oil is extremely hot immediately af­ter the engine is turned off. Coming into
contact with or getting any engine oil on
your clothes could result in burns.

ECS00440

CAUTION:

● Do not run the engine with too much or

not enough oil in the oil tank. Oil could

Storage

ESU12430

Long-term storage requires some preventive
procedures to guard against deterioration.

Cleaning

Thoroughly clean the snowmobile, inside and
out, to remove the corrosive salts and acids
that can accumulate. Use Yamaha Mud,
Grease, and Engine Cleaner, or an equivalent
product, to loosen mud, grease, and grime.
Wash with mild soap, then rinse and dry com­pletely.

Lubrication

Lubricate moving parts, suspension linkage,
and pivot points. Use the grease or lubricant
specified in the MAINTENANCE section, or
Yamaha Lube-Zall general-purpose lubricant.
Proper lubrication fights corrosion while it re­duces friction.

Fuel system

Add Yamaha Fuel Stabilizer and Conditioner,
or an equivalent stabilizer, to the fuel tank to
help prevent fuel oxidation and gum and var­nish deposits, and to inhibit corrosion in the
fuel system and injectors. In areas where ox­ygenated fuel (gasohol) is used, consult a
Yamaha dealer.

Engine

Proper storage of the engine is essential to
prevent costly rust and corrosion damage to
internal engine components. This is more im­portant in areas where oxygenated fuel (gas­ohol) is used, because the alcohol content in
the fuel increases the chance for water to en­ter the engine. Use Yamaha Stor-Rite Engine
Fogging Oil, or an equivalent fogging oil, to
protect both the combustion chamber and
crankshaft from corrosion. An alternate meth­od is to remove the intake silencer and squirt
oil into the throttle bodies while the engine is
running.

ECS00680

CAUTION:

Do not attempt to store the snowmobile by
simply starting the engine occasionally
during the storage period. This can cause
more harm than good! Moisture and acids
form during combustion which can actual­ly increase the chance for corrosion dam­age during the storage period.

Surface protection

Apply a coat of wax to painted surfaces. Apply
suitable protectants to the exterior of the en­gine, drive track, and to other metal, plastic,
and rubber parts.

Battery

EWS00610

WARNING

● Never smoke around the battery while it

is being charged. Sparks may ignite the
hydrogen gas created by the battery.

● Disconnect the negative lead first, then

the positive lead from the battery.

● Connect the positive lead first, then the

negative lead to the battery when install­ing the battery.

● Never connect the battery to or discon-

nect it from the snowmobile while it is
being charged. Sparks may ignite the
hydrogen gas created by the battery.

● Make sure that the battery terminals are

tight.

Remove the battery from the snowmobile.
Store it in a cool, dry place that is above 0 °C
(32 °F), but less than 30 °C (90 °F). Check the
condition of the battery once a month, and
charge it as necessary.

ECS00690

CAUTION:

● Always keep the battery charged. Stor-

ing a discharged battery can cause per­manent battery damage.

75

Storage

● To charge a sealed-type (MF) battery, a

special (constant-voltage) battery
charger is required. Using a convention­al battery charger will damage the bat­tery. If you do not have access to a
sealed-type (MF) battery charger, have a
Yamaha dealer charge your battery.

● Do not charge the battery quickly.

Charge the battery for 10 hours at 1.2
amperes.

Drive track

Loosen the drive track and block up the chas­sis so that the track is suspended above the
ground.

V-belt

Remove the V-belt and store separately.

Storage

Store the snowmobile in a dry, well-ventilated
place out of direct sunlight. Put a fabric cover
over the snowmobile, preferably one that is
designed for it. Do not use a plastic or vinyl
cover—condensation could be trapped un­derneath which could increase the chances of
rusting.

Returning to service after storage

When returning your snowmobile to service,
install the V-belt and battery and adjust the
drive track.

that you have your snowmobile checked and
tuned by a Yamaha dealer. The dealer has
the experience and training to help you get
the maximum performance and use out of

WARRANTY QUESTIONS AND
ANSWERS

Q. What costs are my responsibility during the warranty

period?

A. The customer’s responsibility includes all costs of

normal maintenance services, non-warranty repairs,
accident and collision damages, as well as oil, spark
plugs, clutch drive belts, and slide runners.

Q. What are some examples of “abnormal” strain, ne-

glect, or abuse?

A. These terms are general and overlap each other in

areas. Specific examples include: Running the ma­chine out of oil, hitting an object submerged under
snow, operation on surfaces other than snow or ice,
operating the machine with a broken or damaged
part which causes another part to fail, and so on. If
you have any specific questions on operation or
maintenance, please contact your dealer for advice.

Q. May I perform any or all of the recommended main-

tenance shown in the Owner’s Manual instead of
having the dealer do them?

A. Yes, if you are a qualified snowmobile mechanic and

follow the procedures specified in the Owner’s and
Service Manual. We do recommend, however, that
items requiring special tools or equipment be done by
a Yamaha snowmobile dealer.

Q. Under what conditions is the clutch not covered by

warranty?

A. Clutches as well as clutch components wear with

use. Normal wear is not covered under warranty such
service is the customer’s responsibility. Abnormal
wear is, however, covered for one (1) year from the
date of purchase. Your Yamaha snowmobile dealer
possesses criteria as to what constitutes abnormal
wear.

Q. Will the warranty be void or canceled if I do not

operate or maintain my new Yamaha exactly as
specified in the Owner’s Manual?

A. No. The warranty on a new Yamaha cannot be

“voided” or “canceled.” However, if a particular failure
is caused by operation or maintenance other than as
shown in the Owner’s Manual, that failure may not be
covered under warranty.

requirements to your satisfaction at the time of sale,
and upon your request at any later date.

about this warranty?

questions about this warranty. If the dealer is not able
to do so, he is expected to contact Yamaha Motor
